*While on the toilet, one must remain silent. Talking, answering greetings or greeting others is strongly discouraged.[4]


Haha I was gonna mention that. I'm still not sure if this counts -- probably does. I'll consult a scholar. Because there are similar things which are allowed under Islam. For instance, a Muslim is advised (not commanded) to make ablutions before picking up the Qur'an. But I have a Qur'an app on my phone which made me wonder if I was supposed to make ablutions before opening the app. A scholar of Islam told me that I'm not. He quoted a ruling which reasoned that the purpose of a mobile phone is not just reading the Qur'an; which is also comparable to a book containing Quranic verse - you don't have to be in a state of purity before picking up that book.


> I'm still not sure if this counts -- probably does.

Why do you think it does not count?


Maybe because while reading you're not required to open your mouth and physically speak. That's just my reasoning. Islamic rulings are based on the Qur'an and the Traditions of the Prophet (pbuh). There are about a million traditions on a variety of topics. The scholars keep them in mind while giving a ruling. So, I'm in no position to give a ruling on this. A Google search on the topic tells you that it's not, but none of the answers are satisfying for me so I think I'll have to visit a scholar and ask him/her.


What you mentioned does not cover byzantine faults... pow is the only known solution


There is a large amount of r&d being put into BFT-style proof of stake for Ethereum, it’s always been part of the roadmap. Much work still needs to be done beyond the test net, but so far no fundamental showstoppers have been found. There is also constant collaboration between the researchers and developers of major projects to move the entire field forward.

It’s still early days, unfortunately the hype got far ahead of the tech but progress is being made everyday. I think the same of VR/AR.

If only someone could think to google "BFT Raft extension" or "BFT paxos extension" and find published research. And if only papers from that search had citations. And if only those cited had links to foundational research on generalized BFT strategies. Oh if only we lived in such a world.

If only. If Only. IF ONLY. iF oNLY. If OnLy. iF oNlY.


In cryptography, a ring signature is a type of digital signature that can be performed by any member of a group of users that each have keys. Therefore, a message signed with a ring signature is endorsed by someone in a particular group of people. One of the security properties of a ring signature is that it should be computationally infeasible to determine which of the group members' keys was used to produce the signature. Ring signatures are similar to group signatures but differ in two key ways: first, there is no way to revoke the anonymity of an individual signature, and second, any group of users can be used as a group without additional setup. Ring signatures were invented by Ron Rivest, Adi Shamir, and Yael Tauman, and introduced at ASIACRYPT in 2001.[1] The name, ring signature, comes from the ring-like structure of the signature algorithm.

Linkable ring signatures [4] The property of linkability allows one to determine whether any two signatures have been produced by the same member (under the same private key). The identity of the signer is nevertheless preserved. One of the possible applications can be an offline e-cash system. [link: https://en.wikipedia.org/wiki/Ring_signature]


Linkable ring signatures are problematic because if someone can coerce you into signing a second message then they can identify who you voted for.


There is a cryptographic primitive that does just this allowing of plausible deniability whilst ensuring that only persons able to vote voted: Using Linked Ring Signatures.


Fluid simulation is hard, I found using a curl-noise based fluid simulation works quite well esp for mobile game development


Blockchain would definitely solve this: Traceability, verifiability (no double casting). If you dont trust the counters (which no1 in america should) you can also use a form of Secure Multiparty Computation to hide the outcome from the counters until the last ballot is cast. So ya.


> you can also use a form of Secure Multiparty Computation to hide the outcome from the counters until the last ballot is cast

That sounds like a terrible idea. What happens when somebody tries to hold the election process hostage by not casting a vote?


That will never happen because voting happens during a finite window of time.


The blog is trying to mask wifi probe requests. Active scan and connect modes are disabled on iOS and most modern smartphones from my knowledge. Back in the golden days, we use to track people around based on their wifi signals, we also developed a machine learning system to determine where a person was based on their RSSI over time (we used time warping networks).


I believe recent versions of IOS still do this in some form, but they use random MAC addresses. But even if recent devices don't send out probe requests anymore, there are still many older devices or devices with out-of-date OSes to make this work.

While testing I didn't really have a way see what percentage of devices around me sent probe request, but the absolute amount of devices is still high.


I can understand why many would fail to see the value of this or classify the practice as morbid, most of the people here are from a capitalist upbringing. Here you are taught materialism is eveything. The idea to disconnect from the material and ultimately release yourself from your ultimate possession (your body) is an interesting spiritual practice undertaken by many ancient philosophies. In fact, in India, there is a law that prevents devoted monks from fasting to death for that very reason.


You fail to show that it has any value.

  > disconnect from the material and ultimately release yourself from your ultimate
  > possession (your body) is an interesting spiritual practice
Humans have done that to each other since the very beginning, usually to others but also to themselves. Why you would see that as something of value would surely be interesting for us to read here, also what the difference is between doing it to yourself compared to doing it to others.

I would like to point out though, as a mere materialist but with Eastern Bloc communist upbringing instead of a capitalist one actually, I won't see a reasoning that is based on some state changes happening inside the person's brain as a useful justification, unless that has a (demonstrable) influence beyond that person.

It's not that I'm greatly concerned about what people do to themselves, just that you say we fail to see the value, which is very different and goes far beyond arguing for letting people do what they want if it only affects themselves.
